Via the Transactional Records Access Clearinghouse (TRAC):

(15 Jun 2016) So far in FY 2016, the odds that a noncitizen will be ordered deported by an immigration judge have fallen to a new record low of 42.4 percent. This is the lowest level since at least FY 1998, according to the latest available Immigration Court data covering the period through the end of May 2016.
This is the second year in a row that less than half the deportation orders sought nationwide by the Department of Homeland Security (DHS) were granted by the court, and represents a dramatic change from five years ago. During FY 2011, deportation was ordered 70.2 percent of the time. This fraction fell to 62.6 percent during FY 2012, to 52.9 percent in FY 2013, to 50.7 percent in FY 2014, and was down to 46.5 percent last year.
